Title: Improvements relating to the use of thermionic valves
IPC: H03F3/32
Filed: 1932-12-19
Abstract: 412,182. Valve circuits. MUMFORD, A. H., 27, Grendon Gardens, Wembley Park, Middlesex, and BOURDEAUX, N., 18, Iver Lane, Iver, Buckinghamshire. Dec. 19, 1932, No. 35892. [Classes 40 (iii) and 40 (v).] A valve relay of the reciprocally-coupled type is arranged so that an increase in the anode current of one valve produces a decrease in the anode current of the other and so that the anode currents pass in opposite directions and with a "trigger" effect through a common load circuit. The arrangement is suitable for signalling by direct single or direct double current impulses (marking and spacing) or as a voice-operated relay for preventing "singing." A resistance R2 in the anode circuit of valve VI is in the grid circuit of V2, whilst a resistance R1 in the anode circuit of valve V2 is in the grid circuit of V1. The output or load 4 is common to both valves, though the two anode currents pass through the load in opposite directions. A positive impulse applied to the input terminal 3 increases the current flow through R2 and simultaneously tends to cut off the current through valve V2 by depressing the grid voltage until a steady current flows through the load 4. A succeeding input impulse of opposite voltage reduces the output current from the valve VI. Simultaneously the output from valve V2 increases, and progressively cuts down the output from VI by increasing the negative voltage across R1 until the current through the load 4 reaches a steady valve in the opposite direction. Specification 373,309 is referred to.

Abstract: 901,805. Making sheet materials; brazing. NORTHROP CORPORATION. Oct. 26, 1959 [Oct. 28, 1958], No. 36139/59. Classes 83 (2) and 83 (4). In brazing a honeycomb core panel or like structure the panel components are placed in a flexible metal envelope conforming to the shape of the panel, the envelope is sealed, placed vertically and purged by withdrawing the gas therein and replacing it with non-oxidizing gas below atmospheric pressure with the envelope vertical, the temperature of the envelope and components is raised above the melting temperature of at least certain of the components and then the envelope is rapidly chilled while applying uniform pressure over the sides thereof. A sandwich comprising a honeycomb core 16, Fig. 8, and a pair of panels 18 with a brazing material 20 in foil, powder or other form between the core and panels, is placed in the space formed by depressions 14 in a pair of stainless steel &c. envelope halves 10, Fig. 3, and 12, and the envelope is closed by welding around the edges of the halves. The bottom of the depressions may be covered with a material to prevent liquid brazing metal adhering thereto, a coating of heat-retaining material possibly of varying degrees of emissivity may be provided on the inside and/or on the outside of the envelope to cause more or less heat absorption in panels of varying thickness and a removable mask having cutouts may be placed outside of the envelope to control the heat absorption. The envelope is first evacuated and then inert gas, e.g. argon, helium, &c. is flowed into the envelope and this cycle is repeated several times, finally leaving inert gas below atmosphere pressure within the envelope. The evacuation and introduction of inert gas takes place through conduits 26, 28 arranged in arms 22 of the envelope. The envelope in a vertical position is hooked on a pair of hooks 38 suspended from a roller unit 34 on an I-beam 32 and is moved to between a pair of quartz lamp radiant heaters and gold reflectors 43 constituting a preheater stage. The envelope is then moved to a final, heating pair of radiant heaters and reflectors 44 where the brazing material is melted. The honeycomb cells being horizontal, the cell walls act as dams to prevent flow of the brazing metal to the bottom of the envelope. The envelope is then moved to between dies 46 having solid or resilient faces and movable together to contact the envelope, thus cooling and preventing distortion. The dies may be provided with cooling or heating medium. The I-beam may be vertical or the envelope may remain stationary and the heating &c. means movable. The preheat stage may be dispensed with or more heating stages may be provided and heating stages may be provided beyond the dies 46 for after heat treatment. Diffusion bonding is referred to.

The output of amplifier 10 (Fig. 6) is connected to the common junction of capacitors 12, 13 selectively connectible to one of its input terminals, an unknown analogue voltage E in  being first applied to its other input so that one of the capacitors is charged to this level, a reference voltage E r  then being applied so that the amplifier output drops to E in  - E r , switches 26, 36; 35, 34 being changed over to store this value on the other capacitor. This process is repeated with the amplifier output decreasing in increments of E r  until it changes polarity, detected by comparator 44, the number of switching operations necessary to change the output polarity being indicative of the value of the highest digit of the input voltage E in . The error signal from the amplifier is then multiplied by ten, using a resistor 30 and the process repeated to give the nines complement of the next digit. The count for each decade accumulated in binary form in a ripple counter (Fig. 9, not shown) is decoded to decimal form and applied to the cathodes of gas-filled indicator tubes which are enabled sequentially by a programmer (Fig. 8, not shown) which also controls the switching operation. To indicate the actual value of the second digit and not its nines complement the decoder output may be crossconnected to a cathode of the second indicator tube. The apparatus of Fig. 6 may be modified to accept inputs of either polarity, the initial comparator output being used to derive the sign bit which is displayed. The amplifier is D.C. stabilized at intervals by closing switch 15 (Fig. 6) with switches 14, 16 open so that the input to the amplifier with respect to ground is the D.C. offset voltage #E the capacitor then charging to the output voltage, i.e. -#E.
